Sea Club-rush

A rhizomatous perennial mainly of saline ground or in shallow brackish water, usually rooted in mud but sometimes in gravel and shingle. Coastal habitats include saltmarshes, tidal river banks, creeks, ditches, lakes, ponds, borrow-pits, and also marshes and damp pastures. It is occasionally found in freshwater habitats inland, including flooded riversides and clay- and gravel-pits. B. maritimus reproduces by rhizomatous spread, tubers and seed. Lowland.

Brown Bog-rush

A tussock-forming perennial occurring in base-rich flushes within calcareous grassland, usually adjacent to unimproved heathland. Seed production is low, and dispersal is restricted as the seed is retained in the inflorescence for up to a year. From 200 m above Loch Tummel (Mid Perth) to 390 m as an alien on Ben Vrackie (E. Perth).

Black Bog-rush

A tussock-forming perennial of calcareous and other base-rich fens (especially near springs), and of peaty flushes, marshes, bogs, dune-slacks, sea-cliff flushes, and the upper fringes of saltmarshes where there is base-rich flushing. In W. Ireland, it is frequent on acid blanket-bog. Generally lowland, but reaching 550 m in the Mourne Mountains (Co. Down).

Round-headed Club-rush

In Devon, this rhizomatous perennial herb occurs in damp dune-slacks and on adjacent low dunes, and in Somerset in a damp sandy hollow on a coastal golf course. Elsewhere, it occurs as an alien, especially in industrial areas. Substantial ripening of fruit and seed set appear to occur only after a long, hot summer. Lowland.
